Abstract
A device for supplementing an electrode plate with lithium and a method for supplementing an electrode plate with lithium. The device for supplementing an electrode plate with lithium includes a first lithium strip unwinding mechanism, an electrode plate unwinding mechanism, a roller pressing mechanism, a first traction mechanism, an electrode plate winding mechanism, and a first coating mechanism. The first lithium strip unwinding mechanism is configured to dispose a lithium strip, and the electrode plate unwinding mechanism is configured to dispose an electrode plate. The roller pressing mechanism includes a first calendering roller, a first laminating roller, and a second laminating roller. In a traveling direction of the lithium strip, the first coating mechanism precedes the roller pressing mechanism, and the first coating mechanism is configured to apply a coating layer on a surface of the lithium strip.
